The present invention discloses a rotor of wind energy conversion system (WECS) with the Venturi-tube effect. All the blades mounted on the blade-mounting seat envelop together to form a revolving-body cage turbine, which can be divided from structure into a head portion at the windward end, a tail portion at the wind exhaust end, and an airstream compression portion between the head portion and the tail portion and constituted by the enveloping blades. The revolution diameter of the airstream compression portion is gradually substantially increased from the head portion to the tail portion. The cage turbine forms a dynamic Venturi tube during the revolving process, with which the blade revolves to constitute its outline tube wall with the air permeability. The airstream passes through a window between the blades, and the incoming wind does work towards the blade during the process of permeating from the external space to the internal space of this outline tube wall, thus realizing the energy transfer. |

1. A rotor of wind energy conversion system (WECS) with the Venturi-tube effect, comprising:
a horizontal main shaft with multiple blades positioned around, a blade-mounting seat fixed on the main shaft for mounting the blades, and a connector between them; all the blades mounted on the blade-mounting seat envelop together to form a revolving-body cage turbine with the main shaft as the revolving axle; the blade-mounting seat includes a front blade-mounting seat and a rear blade-mounting seat, with both ends of the blade fixed on the two blade-mounting seats, respectively; the cage turbine includes a head portion at the windward end, a tail portion at the wind exhaust end, and an airstream compression portion between the head portion and the tail portion and constituted by the enveloping blades; the cage turbine forms a dynamic Venturi tube during the revolving process, with which the blade revolves to constitute its outline tube wall with air permeability; and an airstream passes through a window between the blades, and incoming wind does work towards the blade during the process of permeating from the external space to the internal space of this outline tube wall, thus realizing the energy transfer, wherein the blade on the cage turbine is made of a thin plate, whose average width is more than 12 times as large as the thickness of the plate, with the width of the plate connecting the connector, between the blade and the main shaft and not used for accepting or exhausting wind, on the tail blade-mounting seat being less than 12 times as large as the thickness. |
